OK, confirmed.  I set UseSessReg=false in /etc/kde3/kdm/kdmrc, and the problem 
is resolved.

While I was doing this, I noticed the file /etc/kde3/kdm/kdm.options for the 
first time.  This little file has just three options, one of which is 
(no-)use-sessreg.  It has a man page (kdm.options(5)), but the man page 
doesn't say what happens when kdm.options conflicts with kdmrc.  In my case I 
didn't have anything about UseSessReg in kdmrc, but kdm.options included 
use-sessreg.  Now I put UseSessReg=false in kdmrc, and this seems to override 
use-sessreg in kdm.options.  Confusing, but anyway the problem is solved now.  
Thanks for your help.

Andrew.
